Anonymize certain fields during search time field extraction per role

Hi!

I would like to know the best way to anonymize certain fields per role base in search time field extraction.

For example,

If I prepare

userA - roleA
userB - roleB

and raw data ,

a,b,c
1,2,3

i want to make userA see
a,b,c
1,2,3

but userB not see field b
a,b,c
1,0,3

I believe usually this can be implemented in index-time by creating extra index which has field b masked as 0.
But what would be the best way to implement in search time?

Thanks,
Yu

Security is applied at the index layer, any attempts to impose security at search time will ultimately fail if someone is determined. If the data must be hidden, then it must be done at the index level.

Having said that though, if you still want to do it at search time then I would guess you make a pre-defined search or dashboard that extracts a set of fields they're "allowed" to see, and hope they don't fiddle with it or find a way to access _raw.

Hello sciurus.

Thank you for the comment.

I decided to do it in the index level.

Thanks,
